<areece> I've asked a couple of times but wanted to ask a different group: does rust use a custom llvm or can it be linked against the latest llvm release?
<pcwalton> areece: it's custom
<areece> (alternatively, how do I ask the mailing list)
...
<pcwalton> depends on some GC changes that we haven't upstreamed
<areece> pcwalton: so how will it fail if I don't use the custom llvm?
<areece> will it just subtly fail eventually?
<areece> because it builds successfully
<bstrie> it might not fail at all if gc isn't enabled
<pcwalton> if you don't use the GC I think it might well work
